Potential Future Developments

The potential opportunities for making bonded connections in civil engineering structures outlined in this chapter are by no means exhaustive. They represent examples which vary substantially in developmental progress from possibilities to well researched concepts.

As for other recyclable heterogeneous catalysts, zeolites and related materials can also contribute to the development of environmentally friendly processes in the synthesis of bulk and fine chemicals. The concept of a biomass refinery, capable of separating, modifying and exploiting the numerous constituents of renewable resources, is gaining worldwide acceptance today with a very broad outlook. This chapter has attempted to show that this particular area of carbohydrate chemistry is in itself very rich, both in already acquired knowledge and potential future developments.

The fission of one nucleus of produce about 200 MeV of usable energy, to be compared with 4 eV produced by the oxidation of one C atom. During the overall process, a huge amount of heat is produced through a controlled nuclear chain reaction in a critical mass of fissile material. Potential future developments (fission in fast neutron reactors (breeders), also known as fourth generation nuclear, which... 

Considerable interest has evolved over the past decade in the measurement of matrix metalloproteinases (MMPs) and tissue inhibitors of metalloprotei-nases (TIMPs) in blood and urine as an aid in the diagnosis and prognosis of disease. The goal of this chapter is to provide a comprehensive review of the subject with the focus on potential future developments and applications of the technology. 

In parallel to development activities in the materials themselves, significant progress has been made in the architecture of devices. This includes a transition from dense, self-supported membranes to the use of thin films supported on porous substrates, as well as developments in tubular geometries and modified planar geometries. This chapter will provide an outiine of these development activities and provide possible insight into potential future developments. 

There are a few potential future developments. The possibility of combining the position scanned He microbeam NRA technique and the D-( He,p)" He nonresonant nuclear reaction technique to produce three-dimensional profiles has been discussed in the literature. 

Abstract Pervaporation is a peculiar membrane separation process which is currently being considered for integration with a variety of reactions in promising new applications. Indeed, pervaporation membrane reactors have some specific uses in sustainable chemistry, which is an area currently growing in importance. The fundamentals of this type of membrane reactor are presented in this chapter, along with the advantages and limitations of different processes. A number of applications are reviewed with particular attention given to potential future developments. 

Contributiorrs also offer an outlook on potential future developments in the field. 

Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5-10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or to include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the nonspecialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field. 

This chapter will start off by giving a historical overview of the use of EPXMA/CC-SEM/EDX and TW-EPXMA applied to environmental particles, concentrating on airborne particulate matter. The more recent advances where TW-EPXMA is combined with MRS and ATR-FT-IR-IT to elucidate the chemical and structural nature of airborne particulate matter will then be discussed. The few examples where airborne particulate matter has been analysed by SEM/EDX interfaced with MRS (SEMSCA, illustrated in Fig. 1) will be summarised and the chapter will conclude with a view of potential future developments and requirements for further extensions to current practices. 

In this final chapter, we will attempt to review the findings attained during the various steps of theory derivation and subsequent validation as well as to present the prospect of potential future development. 

The primary industrial extractants in use for the separation of rare earths by solvent extraction are di-2-ethylhexyl phosphoric acid (HDEHP), tributyl phosphate (TBP), carboxylic acids, and amines. Many other extractants have been examined and reported in the literature in the search for improving the extraction and separation of individual rare earths. This chapter discusses several of these extractants for their interesting chemistry and potential future development, in addition to the available industrial extractants now in use and proposed for the separation of rare earths. 

This paper presents a review of development in the pneumatic capsule pipeline (PCP) system and its potential future developments. Two commercial PCP systems have been installed in Japan. One is to transport 2 million tons of limestone annually from the mine to the cement works. It has been in operation since 1983 without environmental pollution, with its availability being as high as 94 - 98 %. The other was commissioned for tunneling of Japan s bullet train from 1991 to 1994. This application is an epoch-making tunneling project with cleanliness and safety. Sumitomo Metal Industries, Ltd. (SMI) is also studying the application of the PCP system to municipal solid wastes, parcels, etc. It is anticipated that the 21st century will see widespread uses of the PCP system by virtue of its effectiveness without enviroiunental impacts. 

This chapter is subdivided into a number of sections. This section provides a general background to the development and application of the FEM. O Section 25.2 provides the fundamentals of the method and O Sect. 25.3 discusses some of the practical aspects of finite element modelling. O Section 25.4 discusses application of the FEM to adhesively bonded joints and O Sect. 25.5 provides conclusions from the chapter and indicates potential future developments in the application of FEA to bonded joints.
